Hybrid tea rose plant named `Jacolly`

ABSTRACT

A hybrid tea rose plant having distinctive orange flowers with a yellow reverse on the petals, red bark on main stems and laterals, thick petals, vigorous, upright growth habit, and an attractive exhibition-style flower and bud form.

The present invention relates to a new and distinct variety of rose plant of the hybrid tea class which was originated by me by crossing an unnamed seedling with the variety Aroheddo.

The primary objective of this breeding was to produce a new rose variety having the good bud form of the female unnamed peach-colored seedling combined with the vigor, large flower and upright growth of the male parent. The objective was substantially achieved along with other desirable improvements as evidenced by the following unique combination of characteristics which are outstanding in the new variety and which distinguish it from its parents, as well as from all other varieties of which I am aware:

1. Distinctive orange flower with a yellow reverse on the petals;

2. Vigorous, upright habit;

3. Thick leathery petals;

4. Reddish bark on main stems and laterals; and

5. Exhibition-style bud and flower form.

Asexual reproduction of this new variety by budding, as performed at Wasco, Calif., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

The accompanying illustration shows typical specimens of the vegetative growth and flowers of this new variety in different stages of development, depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

The following is a detailed description of my new rose cultivar with color descriptions using terminology in accordance with the Royal Horticultural Society (London) Colour Chart, except where ordinary dictionary significance of color is indicated.

I claim:
 1. A new and distinct variety of rose plant of the hybrid tea class, substantially as herein shown and described, characterized particularly as to novelty by the unique combination of its distinctive orange flowers with a yellow reverse on the petals, red bark on main stems and laterals, thick petals, vigorous, upright growth habit, and an attractive exhibition-style flower and bud form.
